Given numbers are 620,542,917,178

The least common multiple of numbers can be find using the prime factorization method or LCM formula.

The LCM of 620,542,917,178 is 13712616260.

Find LCM of 620,542,917,178 with Prime Factorization

Multiply the prime numbers at the bottom and the left side.

2 x 310 x 271 x 917 x 89 = 13712616260

Therefore, the lowest common multiple of 620,542,917,178 is 13712616260.

LCM formula is LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}

Firstly, we have to find the product of all the numbers.

620 x 542 x 917 x 178 = 54850465040

Then, let us find the GCF of these five numbers. To do so, we have to list down the factors for each number and choose the highest factor that is in all of the lists.

620 : 1, 2, 4, 5, 10, 20, 31, 62, 124, 155, 310, 620

542 : 1, 2, 271, 542

917 : 1, 7, 131, 917

178 : 1, 2, 89, 178

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 620,542,917,178, is 1.

Now, the common factors can be found like this.

620:2x 2x 5x 31

542:2x 271

917:7x 131

178:2x 89

From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.

2x 2 = 4

Therefore, the value for common factors is 4.

Now that we have all the elements of the formula, we can plug them in to calculate the LCM.

LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}

LCM = 54850465040/(1x4)

LCM = 54850465040/4

LCM = 13712616260

Thus, we can understand that the LCM of 620,542,917,178 is 13712616260.
